    摘要: A method of manufacturing semiconductor device having silicon through via is disclosed, and conductor can be fully filled in the silicon through via. First, a silicon substrate is provided. Then, the silicon substrate is etched to form a through silicon via (TSV), and the through silicon via extends down from a surface of the silicon substrate. Next, a barrier layer is formed on the silicon substrate and in the through silicon via. Then, a seed layer is formed on the barrier layer and in the through silicon via. Afterward, a wet treatment is performed on the seed layer over the silicon substrate and within the through silicon via. The through silicon via is then filled with a conductor.
